ABSTRACT
The article considers the issues of non-repeatability of exhaust emission and fuel consumption test results for road vehicles tested on a chassis dynamometer. Empirical results of passenger car tests on a chassis dynamometer in the WLTC (Worldwide Harmonized Light Vehicles Test Cycle) test were used. Tests were conducted in four repeated sets to assess the repeatability of the test results.
The road emission of hydrocarbons, non-methane hydrocarbons, carbon monoxide, nitrogen oxides, particulate matter and carbon dioxide, the road number of particulate matter and operational fuel consumption were determined.
The coefficient of variation of the values measured in the four tests was determined, taken as a measure of the repeatability of the test results.
The coefficient of variation of the road emission of carbon dioxide and operational fuel consumption is the lowest.
No significant differences were found in the values of the measured exhaust emission.
